Title: Vacuum deposition of compound thin film
Inventor: MASHITA MASAO
IPC: H01L21/203
Filed: 1983-08-19
Abstract: PURPOSE:To effect vacuum deposition of a thin film of an Al compound under high precision control of the growing speed and the composition, by making the relative section of ionization of Al vapor to N1.8-2.1 and monitoring the Al flux with an ion gauge. CONSTITUTION:Evaporation sources 2-4 are placed to face on the ion gauge 7 to monitor the flux and then a holder 5 is rotated to focus the flux on a GaAs substrate 5. The growing speed becomes constant when a substrate temperature Ts<550 deg.C. The bonding speed S under such temperature is assumed to be 1, so that the bonding speeds at various temperatures are obtained so as ratio to 1. And the growing speed of GaAs[RGaAs=1.63X10<13>S.JGa(mum/hr)] is obtained by using the Ga vapor flux JGa based on the molecular motion theory. By using S and the observed value RGaAs, the relative section of ionization of Ga is obtained as IGa=1.5-1.7. Thus, in case of AlAs, SAl=1 and IAl=1.8-2.0 are obtained. By using the average value 1.7 of Iga and the central value 1.0 of IAl, the growing speed RGaAlAs of Ga1-xAlxAs and the composition (x) can be controlled with high precision, the difference between the calculation and the observation values being within + or -2%.

Title: Surface acoustic wave convolver
Inventor: MITSUZUKA SHUICHI
IPC: H01L41/08
Filed: 1990-06-08
Abstract: PURPOSE:To attain a high convolution efficiency, to enhance the temperature characteristic and to improve the yield by employing an InP epitaxial layer in place of a low density Si expitaxial layer in a convolver having a structure of piezoelectric film/insuator/low concentration Si epitaxial layer/high concentration Si substrate. CONSTITUTION:An InP epitaxial layer 12 is adopted for an si epitaxial layer in a monolithic surface acoustic wave (SAW) convolver structure. Since the epitaxial layer 12 and a substrate 11 are differ in the type of waterial in this structure, the lattice constant is different and a hetero bonding is formed. The mobility of electrons in the InPused for the epitaxial layer 12 is larger by sev eral times or over than that in the Si and the low due to joule heat generated in the expitaxial layer 12 is smaller than that of a conventional convolver, resulting that the convolution efficiency FT and the temperature characteristic are improved. Thus, the SAW convolver has a more excellent convolution efficiency and a more excellent tempreature characteristic is realized with high yield in comparsion with that of the convolver of a conventional structure.

Title: Electromagnetic clutch
Inventor: HANABUSA SANEMI
IPC: F16D27/118
Filed: 1999-05-28
Abstract: PROBLEM TO BE SOLVED: To reduce the size and the consumption power of an electromagnetic clutch having a meshing engaging member. SOLUTION: When an electromagnetic 75 is demagnetized, a first dog 721 of a lock gear 72 slidably supported at an axle shaft 59 is engaged with a second dog 441 of a final gear 44 through the elastic repulsive force of a spring 80 and an electromagnetic clutch 73 is engaged. When the electromagnetic 75 is excited, a fiction disc 77 is non-rotatably attracted to the electromagnet 75, and since a cam member 78 relatively rotatably and slidably connected to the friction disc 77 is non-rotatably constrained, relative rotation is generated between the lock gear 72 rotating togetherwith the axle shaft 59 and a cam member 78.  As a result, the moving cam 722 of the lock gear 72 receives a reaction force from the fixed cam 781 of the cam member 78, the lock gear 72 is slid in a non-engaging direction against the elastic repulsive force of the spring 80 and attracted to the electromagnet 75, and the electromagnetic clutch 73 is released from engagement.

Title: Run away deciding method
Inventor: OIKE YOSHITAKA
IPC: G06F11/00
Filed: 1984-07-20
Abstract: PURPOSE:To decide run away of CPU by generating a monitor pulse having little wider time intervals than that of both an intervention request signal (IRQ) and a reset pulse, and judging whether or not there is a response by a reset pulse within the monitor pulse. CONSTITUTION:IRQ with a flag emitted from a timer 7 is inputted in CPU8. CPU8 is identified by this flag. Emitting a rest pulse in the first priority, it is inputted as the reset pulse for FF1, and IRQ is also inputted in monostable multivibrators 4 and 5. A monitor pulse T2 whose time intervals are a little wider than that of IRQ and the reset pulse, is emitted in the multivibrator 4, and inputted to an FF3. At the multivibrator 5, a little wider pulse than IRQ is emitted to input in FF2 and 3 as a clear pulse. As the reset pulse is usually within a monitor pulse, the output of an FF2 is at ''0'' level, and if the reset pulse isn't outputted, the output of an FF1 is kept ''1'' level until a next reset pulse is emitted. The pulse emitted from the FF2 is outputted from an OR circuit 6 to become an alarm pulse.

Title: Structure and method for welding tube body
Inventor: YAMASHITA TETSUO
IPC: F16L13/02
Filed: 1998-06-01
Abstract: PROBLEM TO BE SOLVED: To minimize a residual stress generated in a weld zone on an inner side and restrain the occurrence of stress corrosion cracking by forming a groove on inner and outer sides of a pair of tube body edge part and making a groove angle of the tube body outer side smaller than that of the inner side. SOLUTION: Edge parts of the first tube body 1 and the second tube body 2, on which an X-shape groove 13 is formed, are butted. Since the relation ship between an angle θi of a groove 13a on the inner side and an angle θo of a groove 13b on the outer side of the groove 13 is θi>θo, width dimension of a welding 4b on the outer side is smaller than that of a welding 4a on the inner side. After the welding 4a on the inner side is completed, the welding 4b on the outer side is carried out.  Therefore, when the metal of the welding 4b is solidified, shrinkage force generated in the tube bodies 1, 2 in an axial direction becomes smaller in a case that the width dimension of the outer side welding 4b is made smaller than that of the inside welding 4a in comparison with shrinkage force generated wherein width dimension of the outer side welding 4b is not made smaller than the welding 4a.
